System and Method for Detection and Prevention of Cyber Attacks at In-Vehicle Networks

3. The system of claim 1, wherein the BSUs are configured to block ECUs with detected abnormal communication.

4. The system of claim 1, wherein the BSUs are configured to switch communication from the vehicle bus to the security bus upon detection of a potential cyber-attack.

5. The system of claim 1, wherein the BSUs are configured to reset ECUs with detected abnormal communication.

6. The system of claim 1, wherein the BSUs are configured to use the security bus to perform at least one of: source and destination addressing for messages of at least one compromised ECU.

7. The system of claim 1, wherein the vehicle bus is in communication with a gateway, wherein the gateway is in communication with a third bus, and wherein at least one BSU is in operable communication with the gateway.

8. The system of claim 7, wherein for each bus, at least one BSU is configured to monitor communication to the gateway.

9. The system of claim 1, wherein the security bus comprises at least one of an optical and a copper local area network (LAN).

10. The system of claim 1, wherein the vehicle bus is at least one of CAN Bus 2.0, CAN bus 2.0A, CAN Bus 2.0B, CAN FD 1.0 and ISO-11898.

13. The method of claim 11, further comprising blocking, by the BSUs, ECUs with detected abnormal communication.

14. The method of claim 11, further comprising switching, by the BSUs, communication from the vehicle bus to the security bus upon detection of a potential cyber-attack.

15. The method of claim 11, further comprising resetting, by the BSUs, ECUs with detected abnormal communication.

16. The method of claim 11, further comprising using, by the BSUs, the security bus to perform at least one of: source and destination addressing for messages of at least one compromised ECU.

17. The method of claim 11, further comprising monitor communication to a gateway in communication with the vehicle bus, wherein the gateway is in communication with a third bus, and wherein at least one BSU is in operable communication with the gateway.

19. The BSU of claim 18, wherein the at least one controller is configured to emulate at least one of the ECU and the vehicle bus.

20. The BSU of claim 18, wherein processor is configured to perform at least one of: encryption/decryption of messages, authentication, addressing, message routing, firewalling, storing keys and/or logs, and controlling the ECU.
